More preferably, the primary tobacco material is shredded into strips having a cut width of no less than about 0.25 mm. Even extra preferably, the first tobacco material is shredded into strips having a minimize width of a minimum Fashion tobacco pipe of about 0.3 mm. In addition, or in its place, the first tobacco material is ideally shredded into strips having a minimize width of lower than about 1 mm.
In preferred embodiments, the primary tobacco materials is shredded into strips from a sheet material having a thickness from about zero.05 mm to about 1 mm. Even more preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness from about 0.1 mm to about zero.three mm, most ideally from a sheet materials having a thickness of about 0.2 mm. A tobacco reduce filler in accordance with any certainly one of claims 1 to 9, wherein the primary Filling cut tobacco tobacco materials is shredded into strips every comprising at least a first strip structure comprising a branching node from which a further strip construction branches off, forming an angle with the primary strip structure. Figures 10 and 12 present two examples of minimize strips together with one or more V-shaped construction. Each V construction includes two considerably straight parts forming an angle.
Even more ideally, first tobacco material is shredded into strips having a reduce size of at least about 15 mm. In addition, or as an alternative, the first tobacco materials is ideally shredded into strips having a reduce length of less than about 60 mm. More preferably, the primary tobacco material is shredded into strips having a minimize length of less than about 50 mm. Even more ideally, the first tobacco material is shredded into strips having a reduce length of lower than about forty mm. In preferred embodiments, the primary tobacco materials is shredded into strips having a minimize length from about 5 mm to about 60 mm. The term “sectional minimize width” is used in the present specification to describe the side- to-side width of one such portion of a minimize strip of tobacco material.
Suitable natural tobacco leaf supplies embrace tobacco lamina, tobacco stem material and tobacco stalk material. The pure tobacco leaf material used as the second tobacco materials might include any kind of tobacco leaf, together with for example Virginia tobacco leaf, Burley tobacco leaf, Oriental tobacco leaf, flue-cured tobacco leaf, or a combination thereof. A tobacco minimize filler in accordance with the present invention comprises a first tobacco material reduce in accordance with a first cut specification, wherein the first minimize specification units no less than predetermined first reduce width and first minimize length. The term “filling energy” is used to describe the amount of space taken up by a given weight or mass of a tobacco materials. The higher the filling power of a tobacco materials, the lower the load of the fabric required to fill a tobacco rod of normal dimensions.
For instance, a bimodal distribution might correspond effectively to 2 teams of minimize strips having different common minimize lengths , one group being bigger than the opposite. Preferably, the primary tobacco materials is shredded into strips from a sheet materials having a thickness of a minimum of about zero.05 mm. More ideally, the primary tobacco material is shredded into strips from a sheet materials having a thickness of a minimum of about zero.1 mm.
Should one such particle break at a location in the central V-shaped portion, the two ensuing components of the particles would nonetheless be effectively V-shaped. The highest CCV values had been obtained for cut specification no. 3, which substantially corresponds to particles having a Y-shape. However, it was discovered that when particles have been produced from the identical sheet of reconstituted tobacco according to minimize specification no. three are produced, a big fraction of the tobacco material went to waste. These correspond to the shapes illustrated in Figures 9 and 10, respectively, for which the values of CCV listed within the following Table 3 have been measured. Tobacco minimize fillers based on the current invention may be ready by a method comprising offering a first tobacco materials and cutting the first tobacco materials in accordance with a first minimize specification setting at least predetermined first cut width and first cut length. Tobacco cut filler in accordance with the present invention could additionally be incorporated into a selection of smoking articles.
By way of example, tobacco stems could additionally be ground to a fantastic powder and then mixed with tobacco dust, guar gum, and water to kind an aqueous slurry. This aqueous slurry could additionally be solid and dried to form a reconstituted tobacco sheet. As another, appropriate tobacco materials may be blended in an agitated tank with water to obtain tobacco pipe a pulp. This web is fed onwards to a press, where the excess water is squeezed out of the online. Figure thirteen illustrates an apparatus 30 for the manufacture of a tobacco reduce filler in accordance with the current invention. A net 32 of reconstituted tobacco having a thickness T is unwound off a bobbin 34 and fed to a shredding gadget 36.
Sensors 40 and mass flow controllers forty two, forty four, if current, are operatively connected with a management unit 46 configured to control the operation of the apparatus. In specific, the management unit 46 adjusts the pace to the conveyor belt 38 in view of variations in the speed at which the online of reconstituted tobacco is fed to the shredding device 36, so as to forestall any undesirable accumulation of reduce strips on the conveyor belt. By finely controlling the dimensions and form of the strips into which the first tobacco material is cut or shredded, the options of the first tobacco material can advantageously be higher preserved whenever the primary tobacco material is blended, in the shredded state, with any other tobacco material. This is especially advantageous when the first tobacco material is a pre-processed tobacco material, corresponding to a reconstituted tobacco sheet material. The “thickness” of a cut strip of tobacco materials for incorporation in minimize fillers according to the current invention refers to the distance between an higher surface and a decrease floor of the portion of fabric forming the minimize strip.
